xuezhihua84 2012-04-09 01:35:16

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
DataRowView drv = (DataRowView)e.Item.DataItem;
var peoplerow = (DataSet1.T_PeopleRow)drv.Row;
if (peoplerow.Age > 50)
{
TextBox txtAge = (TextBox)e.Item.FindControl("txtAge");
txtAge.BackColor = Color.Red;
}

}
var peoplerow = (DataSet1.T_PeopleRow)drv.Row;
未将对象引用设置到对象的实例，大牛们看看怎么解决？谢谢了~

你应该加

if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
DataRowView drv = (DataRowView)e.Item.DataItem;
var peoplerow = (DataSet1.T_PeopleRow)drv.R……

DataRowView drv = (DataRowView)e.Item.DataItem;
var peoplerow = Convert.ToInt32(drv["Age"]);
if (peoplerow> 50)
{
TextBox txtAge = (TextBox)e.Item.FindControl("txtAge");
txtAge.BackColor = Color.Red;
}

改成这样后还是出现同样的问题。加了判断行item 不为空

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
//加一行判断
if(e.Item == null) //类似的，判断repeter该行不为空
{return;}

DataRowView drv = (DataRowView)e.Item.DataItem;
var peoplerow = (DataSet1.T_PeopleRow)drv.Row;
